Control and electronics laboratory of the IOC

The control and electronics laboratory of the IOC has the necessary equipment to carry out the experimental work of the research projects and the implementations of the industrial projects developed by the researchers of the control division at the IOC. The members of the division come, for the most part, from the Advanced Control of Energy Systems (ACES) research group until the present SGR call. From the resolution of this call, the research group will change its name to Advanced Control and Power Electronics Systems (ACaPE). The areas of work and research of the members of the group are: control theory and engineering, power electronics and energy conversion and quality problems in electrical networks.

Services it offers

Advanced control for electronic power converters, electrical machines and quality problems in electrical networks.

- Use of advanced modeling and control techniques, such as resonant control, repetitive control, adaptive control, sliding control, energy-based control, control of complex networks, order reduction in models, non-smooth systems

- Application of previous techniques to electric motors and machines: permanent magnet synchronous motors, induction motors, switched reluctance motors

- Application of previous techniques to electronic power converters: dc-dc power converters, ac-dc power converters, multi-phase converters, battery chargers

GAP-NOISE project

Challenge:

Future urban mobility is envisioned with electrified vehicles (xEVs) with driving assistance systems (such as autonomous vehicles, AVs) that coexist with other road users such as pedestrians and cyclists, resulting in smart and sustainable cities with less atmospheric and acoustic pollution. However, one of xEV's most significant problems in urban areas is the lack of noise. The reduction of vehicle noise has been well received by society, but with the inherent risk of losing detectability, with special attention to vulnerable road users. Several studies reported that xEVs are more likely to have more accidents with cyclists and run over pedestrians (especially the most vulnerable such as blind people). External noise is one of the dangers facing xEV tranquility, but internal noise also needs to be addressed. The internal acoustic and vibration environment would help reduce monotony and increase awareness of drivers using automated driving modes (with human feedback still required) and contribute to passenger well-being.

Solution:

The GAP_NOISE project aims to define a set of actions to fill the gap between current knowledge and technology in xEV and human psychoacoustics, combining the fields of electric motor engineering, modeling methods, control strategies, more of the recognized interaction between perceived sound quality. and vibration Thus, establishing a theoretical and practical field suitable for developing a technologically strong community of scientists, engineers and social agents capable of promoting the acoustic integration of autonomous vehicles in future urban areas.
